摘　　要：现有的Web服务框架不能适应普适计算的特点,即无法为移动用户提供自定义的个性化的服务。通过对现有Web服务的扩展,提出了一个觉察上下文的自适应的Web服务开发与部署框架。在该框架中,客户端的上下文信息作为SOAP消息的头块被分布式地传递和处理,Web服务可为客户端提供自定义的个性化的服务。同时,上下文是可扩展的,通过自动的上下文处理,Web服务可自适应新的上下文而不需要改变Web服务本身。The present Web services framework can＇t adapt the features of pervasive computing, which means it can＇t provide mobile users with customized and personalized services. By extending present Web services framework, a new framework for the development anddeploymentofcontext-awareadaptableWebserviceswaspresented. In this framework, context information about clients was treated as SOAP header block, which was delivered and processed in distributed way. Thus Web services could provide clients with customized and personalized services. Context was extensible with new types of information at any time. By using automatic context processing, Web services in the new model could automatically adapt to new context types without any change.
